HENRY J. GAISMAN, OF NEW YORK, N. Y., ASSIGNOR TO GILLETTE SAFETY RAZOR COM- PANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE SAFETY RAZOR Application filed April 17,

My invent-ion relates to improvements in safety razors of the class in which a flexible blade is clamped in a position of transverse curvature between a guard member and a cap 5 or backing member, and an object of my invention is to provide improved means to permit insertion of a blade in shaving position in the razor and its removal therefrom Evithout disconnecting. the clamping memers.

In carrying out my invention I 'provide blade clamping members, a rest for a blade slidable between said members into and out of shaving position, and means to clamp said members against a blade when said rest is in proper position between said members and to release the clamping pressure against the blade to permit said rest to be pulled outwardly for blade replacement.

My invention also comprises novel details of improvement that will be more fully hereinafter set forth. and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part hereof, wherein:

Fig. 1 is an edge view of my improved razor partly in section showing the parts in shaving position;

Fig. 2 is a similar view from the rear of Fig. 1;

Fig. 3 is a section on line 3, 3 in Fig. 1;

Fig. 4 is a view substantially similar to Fig. 3 showing the parts in position for re placement of a blade;

Fig. 5 is a partly broken plan view of Fi 4' FigfGis an inverted plan view of the blade backing or cap-member,- Fig. 7 is a detail edge view of the blade rest,'and V Fig. 8 isa section on line 8, 8 in Fig. 7.

Similar numerals indicate corresponding parts in the several views.

The numeral 1 indicates a guard member 45 and 2 indicates a blade cap or backing mem ber, adapted to clamp a blade 3 therebetween in shaving position. At 4 is a handle rigidly attached to the guard member as at 19.'

- movable. rest for the blade is indicated at5, shown mounted to slide between the members 1931. Serial m. 530,838.

is adapted to slide, said seat being shown provided with inclined spaced guides 7 cooperative with substantially correspondingly inclined sides 8 on the rest 5 whereby said rest is slidably retained on the guard member. A notch or recess at 9, in the outer portion of the rest, permits ready pulling out of the rest with a blade thereon. A stop screw 10 on the guard is adapted to enter a longitudinal recess 11, in the under side oftherest 5, to limit longitudinal movement of the rest in an inward and an outward position, shown in Figs. 3 and 4. The rest 5 is shown provided with projections 12 adapted to receive the apertured portion 3a of blade 3 to position the blade on the rest. The rest 5 is also shown provided with a projection 13 adapted to enter and engage a groove or recess 14 extending longitudinally in the undersurface of the cap or backing member 2, whereby the latter will be retained in proper shaving relation to the blade when the parts are in shaving position, as in Figs. 1, 2 and 3.

The handle 4 is shown provided with a' The guard member 1 is provided with .an

opening 19 in register with the bore in the handle, through which opening the rod 16 may slide, and the rest 5 is shown provided with an aperture or hole 20 adapted to register with the bore in a handle and with the opening 18 in the cap member, when the rest is in shaving position, to permit the rod 16 to pass through the rest, as in Fig. 3. The blade also has an aperture enlargement at 3b to register with the aperture 20 in the rest 5 when the blade is upon the rest and is in shaving position as controlled by the projections 12 of the rest, (Figs. 4 and 5).

In order to permit ready sliding ofthe rest into and from shaving position between the. clamping members 1 and 2, and to retain said members in operative relation, I provide member to move the backing or cap member 2 in a direction away from the uard member when the cap member is released from the rod 16. The spring 23 is shown attached to the guard member by means of screws 24. Said 'spring means may comprise two separate springs or a spring plate divided into two prongs to respectively engage the projections or studs 21, as illustrated inFig. 5.

A spring 25 is shown within the handle portion4aand operative against the handle and against a stop 16a on rod 16, the spring tending normally to push the rod in an outward direction respecting the handle. The stop 1611 may engage the inturned end portion 46 of the handle to limit the movement of rod 16 in an outward direction, as to limit the rod to the position indicated in Fig. i. A'.

fingerpiece 26 on rod 16 permits manipula-' tion of the rod.

When a blade is to be inserted in the razor the rod 16 is rotated to release it from the backing member 2, whereupon the spring 25 will push the rod outwardly, out of the path of the rest 5, and the spring means 23 will push the projections or studs 21 outwardly to move the cap or backing member 2 away from the blade and the rest 5, the heads of the studs engaging the guard member, as in Fig. 4. Said rest 5 may be pulled outwardly carrying the blade with it, as in Figs. 4 and 5, whereupon a used blade may be removed from the.

rest and may be replaced by a new blade.- The rest carrying the new blade may next be pushed inwardly, to the position shown in Fig. 3. v The rod 16 will next be pushed inwardly to engage its threads 17 with the threaded opening 18 of the cap or backing member 2, and then by rotating the rod said cap will be drawn toward the blade for flexing and clamp-ing the blade between the cap and the guard member, and the blade will be retained in shaving position as in Figs. 1, 2 and 31 i My improvements are simple in construction and enable the guard and the cap or backing members to be retained together at all times for cleaning and blade replacement,

thereby overcoming the necessity of separate-,

ly handling the guard and blade backing members for cleaning as is customary in well known types of safety razors.
